I had sudden pain in my left ring finger at the middle knuckle. There was no trauma or bite. The pain lasted for several minutes then went away completely. The knuckle then looked swollen and blue like a vein . This morning the knuckle is purple like a bruise . What could have caused this. Should I worry about a blood clot. I am a healthy 38 year old woman.
